We build unique and custom 300 Blackout AR Uppers that aren’t found by competitors. Quality is a big deal for us. Nobody wants to have problems with they take a trip out to shoot. That’s why we use a special pistol gas system on our 16″ barrels to compensate for most of the different grain bullets for the 300 AAC Blackout. We also warranty all of our AR-15 Uppers for one year of personal use. We use nitrided barrels and stainless steel barrels with our custom muzzle devices.
